Application ined November ai, i922. seriai No. 602,356.

To all whom t may concern.' f

Be it known that I, GEORGE H. BAMBERGER, a citizen of the United States of America, residing at Baltimora, in the county of Baltimore City and State of Maryland, have invented certain new and useful Improvements in Bedspring Fabrics; andI doihere? by declare that the following is an full, clear, concise, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in bed springs, having for an object to .pro-

i vide a novel form of bed spring so constructed as toV combine in a single construction the desirable qualities of resiliency of a spiral spring and those desirable qualities of durability and tenacity `of a link fabric spring, the arrangement being suoliy that with the application of uneven weights or stress to two different portions ofthe iinproved spring, the same will ben iiexed yat such points of application and evenly and uniformly distribute the stress throughout the entire construction without the recognized objectionable center flexing or sagging of the spring, which, as will be understood, would cause the several objects of uneven weight to commonly` move into the pocket so formed withv the re sultant discomforture, as when such objects are persons of different weights,

It is also an Aobject of the kinvention to provide a bed spring which with the application of weight to but one side portion thereof will be eXed only at that particular point of application to resiliently absorb and support the same. f

Another and equally important object of the invention is to provide a bed spring wherein the spring and connecting and supporting elements thereof are so relatively arranged as to cooperate for the even diffusion of weight or stress throughout the same, as a unit, and at the same time, will so function as to brace each other, hence, lendingy materially to its durability and strength. Y

Yet another object of the invention is to provide a bed spring employing side bracing strips or struts which will function withl the application of weight or stress thereto,

to prevent sidek or marginal sagging ofthe spring or the engaging or resting yof the side portions of the spring upon the side support bars 'of thev spring frame and yet, permit of ample movement of such side portions of the spring for absorbing and resiliently supporting such weight.

Other'objectswill bein part obvious and in part pointed out hereinafter.

In order that the invention and its mode companying `illustrative drawings, and in the detailed following description based ,y thereon, set out one possible embodiment of the same.

In these drawings z- Figure l is a plan view of my improved spring having theintermediate portion of of roperation may be readily understood by f persons skilled in the art,I have in the acors thesame and-the frame supporting it broken'l y Figure L is an enlarged fragmentary dei tail in perspective showing the novel form of connection as between the parallel longi-' tudinally disposed series of supporting links and the helical springs. l f

Having more particular reference to the drawings, in connection with which like characters of reference will designate corresponding parts throughout, the invention may be stated to comprehend a substantially j rectangular frame composed of jointed angleiron barsy indicated in its entirety by the numeral l, the head and foot barsof the frame being arranged above the side bars in the manner shown in the Figure 2,

as is coinmonin the art. n n y The improved spring fabric comprises a plurality of spaced parallelseries of longi#y tudinally disposed links generallyindicated ly jointed at their adjacent ends by means of rings 3, which, as will be noted,are `of `a size or diameter sufficient to permit of looseor free relative pivotal movement as `between the ends of saidlinks 2 so jointed. These parallelly arranged series of loosely t jointed longitudinally disposed links 2 as will be noted upon reference to they Figure' l, are arranged within the sidemembers of the spring supportingframe l and are of different, lengths, the longer of the series ioo fby the numeral 2,'said'links being loosee f being arranged alternately of the shorterY thereof. YUpon the free ends of the outermost linksof the various series of the same, other rings 4 areloosely connected or re-v Vthe same arefalternately arranged, that is, to one end of one series of loosely jointed-` links, a short spring 5 is connected Vfor effecting connection of the same with the adjacent foot or head piece frame, While to Vthe opposite Vend of said series of ylinksfa long spring 6 is connected whereby to effect connection of that particular end With'the corresponding foot orv head piece of the spring frame 1.V This arrange- Y ment is clearly shown in the Figure l.V

If desired, oneor more of the series' of loosely jointed links 2 may be provided With a different disposition of the links, that is,

Vinstead of single longitudinally disposed loosely jointed links such as indicated by the numeral 2', pairs of links may be arranged in juxtaposed relation as indicated by the numeralV 7 and have their adjacent ends loosely inter-connected by rings 8 Vcorresponding to the rings 3. Pie plates 9 hav- Y ing spaced openings therein are connected 7 are contractile coiled springs generally to the opposite end of the series ofA links and receive therein the adjacent ends of coiled springs generally indicated by the numerals l() and 11, the springs l() being of lengths less than the lengths of the springsll and thus corresponding to the arrangement of the springs 5 and 6, as heretofore described. 'Byv this latter arrangement of the links 7, the spring fabric will be positively divided into sections as WhereV a spring of size adaptable for use upon'a double bed is employed. y

Arranged between the various parallel longitudinally disposed series of links 2 and I' indicated by the numerall2, said springs being arranged in substantially Vv-shaped pairs, as shown 1n the Figure l, and extending inV Zig zag or substantially V-'shaped Y. rings joining the adjacent ends of one seriesV :formation transversely throughout the Width ofthe bed spring fabric.l Certain ofthe ends of these vcoiled springs l2 are bentor Votherwise engaged with the adjacent of the longitudinally.disposed links, While theopposite ends of the springs are similarly engagedr With the diagonally opposite of the springv rings 3, or 8 of the adjacent or next longitudinally disposed series of links.

It should be here noted that the type of coiled springs 5, 6, 10 and l2 employed in the production of my improved spring is of theexpansion and compression or give Vand take design and in consequence, Will act to function With the application of Veither pull or thrust thereto.

Due to the peculiar Zig zag or V-shaped transverse arrangement or coiled springs l2 in the improved spring fabric, it Will be understood that they will function to effect a resilient and Weight absorbing connection as between each individual longitudinally disposed lseries of loosely jointed links 2 or 7, and in consequence,V with the application-or Weight or stress to any one point of the spring fabric so Vconstructed, iiexing of said `fabric only at that point Will occur. Yet, at the same time, that portion'of the fabricy in proximity-to the portion being flexed under stress orY Weight will have'a portion of the same imparted thereto and in consequence, said stress or Weight Will be evenly diffused throughout the spring construction hence,

permitting the latter to effectually and Vresiliently support the same.

Also, by reason of the alternate arrangement of the long and short springs 5, 6,v

formation of the Y l() and 1l with respect to the free ends of -V the longitudinally' disposed series of loosely joined links 2 and 7, the application of stress or `Weight thereto will, be more evenly and 'uniformly diffused throughout the spring construction. For example, it is an accepted fact that the resilient qualities of a spring increase With the length-of the same and in consequence, by alternately connecting long and short springs to the opposite ends YVof the longitudinally Vdisposed rows of links,

it will beunderstood thatv the spring supporting qualities of the bed spring fabric Vfrom either' of its longitudinally disposed ends Will Ybe vthe same., Thus, Where a greater Weight is appliedto either end of the spring fabric and to the oppositeY end thereof, the capability of theV spring to yieldably support the same will be in no Way. detracted from, since the short springs will provide. a morerigid support, Where- 'as the longer springs Will afford a more yieldable support.V AThus, a marked advantage is secured over those forms of spring Afabricswvherein a transverse seriesv of long springs isV employed for connectingY oneend of the spring fabric to an Yadjacent endV of; the bedspring frame, Whereas a transverse. seriesV of short springs isv employed to connect Vthe opposite end thereof y to its Vparticular end of the kspring frame. Furthermore, `by interposing, alternately, the long springs, it will be understood that a greater resiliency Will-'be afforded by the i these struts 13 and Maarre Q;

spring than would result from the use of a plurality of transverse series 'of short springs, whereas the stability of the spring construction is increased by the interpositioning of the short springs between kthe long springs thereof. f

lo prevent undue side Hering or sagging of the opposite side portions of my iniproved spring fabric, l may and preferably do employ bracing strips or struts indicated by the numeral i3, consisting of lla-t strips of metal of lengths slightly less than the lengths of the spring supporting frame l. @pairings are formed in the opposite ends of serve to permit the connection of the adjacent ends of pairs of give and take coiled springs l/l thereto, the opposits end of suoli springs being lixedly connected to the adjacent outer end portion of the lie-id and foot pieces of the spring frame l in the manner shown in the Figures l and lli/fetal straps or links l snugly embrace e `truts 13 at points equidistant through- 'i their respective lengths and are loosely connected at their inner ends to the adjacent rings 3 inter-connecting the various links of the outermost longitudinally7 disposed series thereof, as shown in the Figure 'l and in this way, it will be understood that a lient yet bracing connection between the side portions of the spring fabric and the bracing strips or struts 13 will be afforded. llccanse of this connection, a bracl nfl aulencc, excessive flexing or sagging of the opposite side portions of the spring fabric to an extent Wliereat the same will strike, en-

or upon the longitudinal side pieces of the spring frame l will be prev jrtcd. `Yet, the resilient supporting qualities of the side portions of the spring fabric will be in no way detract/ed from. Also, it will be understood that because of the loose or pivotal connection as between the braces 'truts i3 and the side portions of the Lic, the latter will be permitted to ly function to absorb and resiliently weight or stress directed tbereonto. ai'ufestly ie construction shown is can, :le of considerable modification and such l ss is within the scope of iny "leider within the spirit of my l il: 'f fabric comprising a pluseries of loosely joined disposed comparatively rigid itudinally disposed rows of spaced diagonally extending; coiled springs arranged in substantially Z-sha-ped trans- 1" l between said parallel series of connected to the same adjacent their loose jo' intures. 0 A bed spring fabric comprising a pluof parallel series of loosely joined n will be entailed and in conse-V frame,
